Application filed May 31, 1906. Serial No. 319,478

To all whom it may concern:

Be it known that I, SAMUEL T. PARK, a citizen of the United States,residing in Danville, in the county of Vermilion and State of Illinois,have invented a new, and useful Improvement in Draft or Work Indicatingand Recording Mechanism for Locomotives or other Traction-Motors, ofwhich the following is a specification.

My invention relates to improvements in mechanism for indicating andrecording the draft or work done by locomotives or other tractionmotors, and more particularly to improvements upon the draft indicatingmechanism of the J. E. Phillips patent No. 428,17 of May 20th, 1890. v

The object of my invention is to provide a draft or work indicating andrecording mechanism for use upon locomotives or other traction motorswhich will be of a simple, efficient and durable construction, capableof being easily and conveniently applied, and which will not onlyindicate to the engineer or driver the draft or load upon thelocomotive, the speed of the train and the work it is doing from time totime, but which will also automatically record in a permanent record ofconvenient form, the performance of the locomotive during the whole timeof its trip from beginning to end, so that the proper ofiicers of therailroad may have all the data necessary for ascertaining or figuring.out the work done by the locomotive and its cost either in terms ofpower exerted, or coal consumed in respect to train or freight loadhauled and its speed, or in any other convenient terms or factors.

My invention consists in the means I employ to practically accomplishthis object or result. That is I to say, it consists in connection withthe draw-bar of the locomotive or its tender, of a fluid containingcylinder and piston intcrpose between them, a pressure gage indicatingthe pressur upon the fluid and thereby the load or tractive pull of thetrain, and having a stationary graduated dial on the gage for indicatingthe tonnage of the train or freight load in train tons, andprovidedavith a movable indicating finger actuated by the fluid cylinderand piston, a movable record sheet, a clock mcchanismfor actuating therecnrd sheet, and amovable recording arm actuated by the fluid cylinderand piston, whereby in'connection with the tons of revenue or payingfreight upon the train and the amount of coal consumed on any trip orhaul, the complete work done .by the locomotive during the whole time itis in use on any trip or haul may be automatically recorded in permanentform, so that the actual cost ofhauling the freight in tons per mile maybe readily arrived at. In my invention, all the necessary factors areautomatically recorded indicating and recording mechanism embodying myinvention as applied to an ordinary locomotive and tender. Fig. 2 is aplan view. Fig. 3 is a central vertical section on line 3--3 of Fig. 2.Fig. 4 is an enlarged plan view partly in horizontal section on line 44of Fig. 1. Fig. 5 is an enlarged detail front elevation of theindicating and recording mechanism. Fig. 6 is a vertical section on line6-6 of Fig. 5, the clock mechanism being simply-conventionally indicatedby a rectangular dotted line. Figs. 7 and 8 taken together indicate onehalf of the stationary dial and one half of the graduated record sheet.Fig. 9'is a side elevation partly in central vertical sectionillustrating a'modification in which a ribbon record sheet is employedin place of the circular record disk illustrated in the previousfigures; and Figs. 10 and 11 are views illustrat-- ing the graduationsupon the record ribbon illustrated in Fig. 9.

In the drawing, A represents a locomotive or a portion thereof, A itstender and A the draw-bar, (preferably the draw-bar at the rear end ofthe tender which connects the locomotive with the train) to whichdrawbar the mechanism of my invention is directly connected. 7

B is the fluid cylinder and B the piston which are interposed betweenthe draw-bar and the tender or locomotive to which the draw-bar isconnected.

The piston B of the fluid cylinder 13 is prcfcrably connected tothedraw-bar by a cross-bar (3,,c0n1iocting rods (3 and cross bar C thecross bar 0 being connected to the draw-bar by a'pin C and the cross barC being connected to the piston B by a pin C D is a pressure gage, thesame being of any suitable or desired construction. It is connected by apipe D with the fluid pressure cylinder B, the gage being preferablylocated in the locomotive cab in convenient position for observation bythe engineer.

The pressure. gage D is furnished with a stationary dial D graduatedpreferably to indicate freight load in train tons. The pressure gage Dmay be of any suitable or well known construction, but it preferablyconsists essentially of a hollow tubular spring arm d communicatingwith'the pipe D, so that the pressure of the fluid tends to straightenout the hollow curved arm d. The free end of the hollow, curved, tubulararm d connected by a link d toothed segment 01 and gear d with thesleeve or hollow shaft (1 of the pressure indicator hand E, so that thepressure indicator hand is caused to rotate around the dial D as thefluid pressure in the cylinder B varies with the load or pull of thetrain.

F is a clock mechanism of any well known or suitable construction and Fis a shalt connected with and driven by the clock mechanism, furnishedwith clamps or holders f f for receiving and supporting a movable recordsheet G, preferably of paper, which is moved or rotated by the clockmechanisms H is a recording arm having a recording marker h, such as apen or pencil, adapted to make a mark ,or record upon the movablerecording sheet G as the same is moved or rotated continuously by theclockv mechanism. The recording arm H is pivoted to the stationary dialat h and is connected by a lever 71 and links k h with the hollow curvedpressure gage d, so that the fluid pressure exerted by the train orlocomotive upon the fluid cylinder and piston 13 B Will be communicatedto the recording arm H. The movable record sheet G may be of anysuitable form adapted to be operated by the clock mechanism,andcooperate with themovable recording arm Hand the fluid cylinder andpiston which actuate the same. I prefer, however, to make it in the formof a circular disk, and 1 preferably graduate it with suitablegraduations and figures to indicate directly thereon the desired factorsor data registeredby the recording arm. If, however,

a plain recording sheet is employed having no figures or graduationsthereon, the record made by the recording arm and its marker may be readby placing the record sheet in juxtaposition with a suitable graduatedreading plate having the necessary graduations and figures thereon. l

the drawing. As illustrated in these figures, which show one half of theentire record sheet, (the drawings being necessarily enlarged in orderto clearly illustrate the graduations and figures or markings) themarking or graduations upon the record sheet preferably comprise aseries of circular lines g, every eighth line I of which is preferablymade heavier to facilitate the reading of the record by tracing the lineindicated by the marker h of the recording arm H.

The space occupied by the circular lines g is that in which the recordto be preserved is kept, and will gage D, which if continued wouldintersect the center of the record sheet G. The time required for anypart of any of these twenty-four sections to pass a given stationarypoint is one hour, and I prefer to divide each of said sections, bylighter bicircular coordinates 9 into spaces representing fifteenminutes or one-fourth of an hour, and the fifteen minutes spaces may, ifdesired, again be divided into smaller fractions representing minutes.

The section G of the record-space, the outer end of which coincides withthe horological space marked G, is indicated by the legend Tractiveforce in 1000 lbs. the next section G to the left is-indieated by thelegend Freight load in train tons, and the next two sections G to theleft by the legend Total resistance of train in tons. The next twosections G G Whose outer ends coincide with the horological spaces 7 and8 are indicated by the legend Speed in miles per hour, and likewise bythe words Horse power at miles per hour, and each succeeding pair ofsections 1 Cr and G G and G8 G in the coupled order designated areindicated in like manner by said words. The sections hereinbeforercferred to cover one-half of the record-space, and this order ofindicating is repeated in the remaining sections which occupy theremaining half, (not shown) of said record-space, and have their outerends coincide in position with the horological spaces markedrespectively with the numerals 13 to 24 inclusive. In section G thecircular lines 9 are numbered, commencing with the innermost to theoutermost, from] to .56 inclusive; but in order to, economize room thenumerals designating the oven numbered lines are arranged in one column,and the numerals designating the odd numbered lines in another column,substantially as shown. In section 'G ,in which the freight loads intrain-tons are to be indicated, the'liues commencing with the innermost,are designated with the numeral 100 and progress to 5600 for theoutermost. one hundred tons representing the smallest train load andfifty-six hundred the maximum. These numerals are placed or printedover'the lines, and the odd numerals are arranged in one column and theeven numerals in another column. In section G the innermost circularline is designated by the numerals 250 and the enter one 14000, and thenumerals ending with the figures 250, or 750, are arranged in onecolumn, and those ending with the figures 500 are arranged in anothercolumn.

The sections G (1: G G, G G and G G each have tables of suitabledisposed figures to indicate the horse power at miles per hour, andthese figures are arranged so that allowance will be made for the factthat a greater tractive force is required to overcome the resistance ofthe train when it is at a standstill than when it is in motion. When thestanding resistance has been overcome, this tractive force is reducedjndraft and consumed in velocity. The starting resistance of the trainbeing known and the resistance of the same While traveling at a givenvelocity, the lesser velocities can be marked and noted by the readingson record G, due to the falling of the indicator-hand E. These readingsare easily ascertained by tracing the tangentially disposed lines 9 g towhere they intersect lines g g. The speed in miles per hour being knownby the bicircular coordinates g, and the tractive force exerted beingalso known, the horse power in lines 9 is easily ascertainable.

In the modification illustrated in Figs. 9, 10 and 11, a differentconstruction of pressure gage is shown and the movable record sheet isin the form of a ribbon G instead of a circular disk. In thismodification, the graduations and markings upon the ribbon are substantially the same as upon the disk and need no I and actuated by saidpressure gage and a stationary dial,

'cylinder and :piston interposed between the draw-bar and holder for arecord sheet actuated by said clock mechanism, and a recording armconnected with and actuated by the pressure gage, substantially asspecified.

further description. The ribbon record sheet G is mounted upon spools ordrums G G, one of which is connected with the shaft F which is driven bythe clock F. In this modification, the gage comprises a cylinder M andpiston M the cylinder containing a spring N, and the piston having astem m, which is connected by a rod m with a slide in carrying themovable recording arm H having the marker h.
